Change Log

All notable changes to this project will be documented in this file.

3.4.0

  • [java-api] SecurityContext has been extended with a thread local storage for Service Plans. setServicePlans(), getServicePlans(), clearServicePlans() methods have been added.
  • [java-security]
    • added support for Identity Service Proof Token validation. Proof Token validation can be enabled by calling JwtValidatorBuilder.enableProofTokenCheck(). Once enabled, it will forward the X509 client certificate from the request header x-fowarded-client-cert as x-client_cert header to the /oauth2/token_keys endpoint.
    • DefaultOAuth2TokenKeyService saves the service plans from response header x-osb_plan (identity broker service plan) in the new SecurityContext thread local storage for Service Plans. The header should be available when proof token validation is enabled. In this case, a x-client_cert is sent in the request to /oauth2/token_keys which should trigger the x-osb_plan response header.

3.3.1

✅ Resolves a Breaking Change introduced in version 3.3.0. Consumers should be able to update to 3.3.1 from a version < 3.3.0 without having to adjust test credentials used in their unit tests when using java-security-test or spring-xsuaa-mock.

In version 3.3.1, when java-security-test is loaded (which should only occur during testing), credentials with localhost as the uaadomain (XSUAA) or trusted domains (IAS) can be used to validate tokens that include a port for localhost in their jku (XSUAA) or issuer (IAS). It's important to note that token validation is less strict in this case and may accept certain edge cases of malicious tokens that would not be accepted in a production environment.

Dependency upgrades

  • Bump spring.boot.version from 3.1.5 to 3.1.6
  • Bump spring.core.version from 6.0.13 to 6.0.14
  • Bump spring.security.version from 6.1.5 to 6.2.0
  • Bump apache.httpclient5.version from 5.2.1 to 5.2.3
  • Bump wiremock.version from 3.0.0-beta-10 to 3.3.1 and replace org.wiremock.wiremock-standalone with com.github.tomakehurst.wiremock
  • Bump logback-core, logback-classic from 1.4.6 to 1.4.14

3.3.0

Breaking Change ⚠️ [java-security-test] (Resolved in version 3.3.1): To validate mocked XSUAA tokens issued by java-security-test module, the UAA_DOMAIN property of the service configuration must now include the full address of the Wiremock server in the format http://localhost:\<PORT>.
Likewise, for validating IAS tokens issued by the java-security-test module, the trusted domains array of the service configuration needs to include the Wiremock URL including the port but NOT the protocol, i.e. in the format localhost:<PORT>.
The full wiremock URL including http:// and <PORT> is available via SecurityTestContext#getWireMockServer#baseUrl.

  • [java-security]

This adjustment ensures that the logic is in line with the 2.x major version.
  • [token-client] reverted removal of OAuth2ServiceException.getHttpStatusCode()

Dependency upgrades

3.1.0

❗ IMPORTANT Update

The zone_uuid claim in Identity service tokens has been deprecated and is now replaced by the app_tid claim. You should use the app_tid claim to identify the unique tenant id, which was previously referred to as the zone.

  • [java-api]

    • HttpHeaders constants are extended with X-app_tid abd X-client_id headers
    • JWKs fetch from identity service going forward requires mandatory headers: X-app_tid abd X-client_id this has been updated in the default implementations of the OAuth2TokenKeyService:
      • DefaultOAuth2TokenKeyService
      • OAuth2TokenKeyServiceWithCache (java-security module)
      • SpringOAuth2TokenKeyService
  • [java-security] AbstractToken is serializable fixes #1209

3.0.0

Baseline changes

cloud-security-services-integration-library requires

  • Java 17
  • Spring Boot 3.0.x
  • Spring security 6.0.x

Breaking Changes

  • Identity service configurations need to provide domains via String array in JSON key 'identity.credentials.domains'. Providing String values under key 'identity.credentials.domain' is not supported anymore. IAS configurations from service bindings have been generated like this for a long time already. This should only affect old configuration files manually written for testing.

  • [token-client]
    • DefaultHttpClientFactory does not longer log warning messages in case of cert-based Apache Http Clients.
    • Usages of HTTP Clients as part of this client library are depicted here.

    • In case there is no certificate given in VCAP_SERVICES a default http client gets created (HttpClients.createDefault()) and the message is still logged with severity WARNING .

Details DefaultHttpClientFactory

It sets

  • connect timeout = 5 sec
  • connection request timeout = 5 sec
  • socket timeout = 5 sec

Furthermore, it makes sure that per client id SSLContext, SSLConnectionSocketFactory and PoolingHttpClientConnectionManager are created only once per instance.

It introduces a PoolingHttpClientConnectionManager and limits

  • maximum connections per route to 4 (default is 2)
  • and the maximum connections to 20

    • JwtIssuerValidator.java supports custom domains of identity service. If ias_iss is given and not empty, JwtIssuerValidator.java checks whether its a valid url and checks whether this matches one of the valid domains of the identity service. The check whether ias matches to any given domains is skipped in that case.
    • The token keys cache does not accept cache time longer than 15 minutes.
  • [spring-xsuaa] and starter
    • As of Spring Security version 5.5.0 only BadJwtException results in InvalidBearerTokenException, which are handled and mapped to 401 status code. Consequently, XsuaaJwtDecoder raises BadJwtExceptions instead of JwtExceptions.
    • XsuaaTokenFlowAutoconfiguration supports X.509 based authentication. You need to provide org.apache.httpcomponents:httpclient as dependency.
    • IasXsuaaExchangeBroker can be configured with (autoconfigured) XsuaaTokenFlow to enable X.509 based authentication.

  • [java-api] [java-security] allows hybrid token creation via Token.create(String encodedToken). The feature is available when using token authenticator. In order to avoid ServiceLoader issues, make sure that you don't mix up different versions of these client libraries. E.g., its not possible to use com.sap.cloud.security:java-api:2.8.3 together with com.sap.cloud.security:java-security:2.8.2. See also here.
  • [samples/sap-java-buildpack-api-usage] uses SAP Java Buildpack BoM (sample).

  • spring.security.version 5.3.5.RELEASE --> 5.4.2

2.8.0

  • [java-security]
    • getClientId() method was added to Token interface. getClientId() method should be used instead of getClaimAsString(TokenClaims.XSUAA.CLIENT_ID). TokenClaims.XSUAA.CLIENT_ID is deprecated.
    • Supports IAS token validation. IAS_SERVICE_NAME has not be provided any longer. You can find a sample here.
  • [java-security-test] In case you like to overwrite the client id using JwtGenerator using withClaimValue() or withClaimValues() method, it's recommended to set the azp claim instead using withClaimValue(TokenClaims.AUTHORIZATION_PARTY, "T000310").
  • [spring-xsuaa]
    • getClientId() method implementation of Token interface has been changed. Using azp and as fallback aud and cid claims to obtain client id.
  • ⚠️ backward incompatible change: usage of deprecated org.springframework.security.oauth:spring-security-oauth2 dependency in OAuth2AuthenticationConverter was removed. OAuth2AuthenticationConverter.convert() method return type has changed from org.springframework.security.oauth2.provider.OAuth2Authentication to org.springframework.security.oauth2.server.resource.authentication.BearerTokenAuthentication
    • Migration tips
      • when necessary, org.springframework.security.oauth:spring-security-oauth2 dependency need to be provided explicitly
      • OAuth2WebSecurityExpressionHandler() won't work in conjunction with OAuth2AuthenticationConverter, as it expects OAuth2Authentication class instead of BearerTokenAuthentication when deriving authorization claims. Use hasAuthority() or hasAnyAuthority() instead of explicitly defined expressionHandler(new OAuth2WebSecurityExpressionHandler()) and access() expression for authorized requests.
  • The following dependency was removed:
    • org.springframework.security.oauth:spring-security-oauth2
  • The following dependencies were updated:
    • spring.boot.version 2.3.4.RELEASE --> 2.3.5.RELEASE

  • [spring-xsuaa] Update Spring versions
    • spring.core.version: 5.2.7.RELEASE --> 5.2.8.RELEASE
    • spring.security.version: 5.3.3.RELEASE --> 5.3.4.RELEASE
  • [java-security-test] SecurityTest and SecurityTestRule provides a better support for integration tests with a mockserver. It is now possible to upload the configuration and the token from a json file. Take our integration tests as a sample java-security-it.
  • [java-security] DefaultJsonObject.getAsStringList(propertyName) parses the JSON object for a given property and returns a String list. This works also in case the property is not a JSON array but a JSON String.
  • [java-security-it] New integration test project. Existing integration tests have been restructured and moved here. Additionally, JWT token validation performance tests have been added for java-security and spring-xsuaa.

2.7.6

  • Fixes ClientCredentialsTokenFlow.scopes() and UserTokenFlow.scopes() to support multiple scopes. The scope form parameter has to provide a space-delimited list (and not comma-delimited list).
  • [java-security] Improve compatibility of SAPOfflineTokenServicesCloud
    • There was incompatibility in the implementation of SAPOfflineTokenServicesCloud that caused the remoteUser of the HttpServletRequest to always return the client id of the XSUAA service binding. This was changed so that it now works like in the old implementation. This means that the remoteUser now returns either the user_name claim of the token for user tokens or the value of the client id cid claim of the token for all other tokens (e.g. client tokens).

2.7.5

  • [java-api] AcessToken provides
    • getAttributeFromClaimAsString(String claimName, String attributeName) to access for example ext_attr values such as subaccountid
    • getAttributeFromClaimAsStringList(String claimName, String attributeName) to access for example xs.user.attributes values such as custom_role
  • [java-security] provide debug logs for failing token validation, see troubleshoot.
  • [java-security-test] Fixed default value for jku token header to http://localhost/token_keys
  • [samples] Upgraded approuter version to "^8.2.0"

2.7.4

  • [java-security] Audience Validation validates to true when the derived client_id of broker-clone token matches the trusted client. This is relevant to support tokens of grant type user_token that contains no scopes.

2.7.3

  • [java-security]
    • Audience Validation is skipped when client_id of token exactly matches the trusted client. This is relevant to support tokens of grant type user_token that contains no scopes.
    • provides the subaccount identifier from the ext_attr claim.
  • [spring-xsuaa] provides the subaccount identifier from the ext_attr claim.

2.7.2

  • [java-security]
    • Audience Validation accepts tokens of grant type user_token that does not provide aud claim. In that case JwtAudienceValidator derives the audiences from the scopes.

❗ IMPORTANT Update

  • Use getSubaccountId() only to fetch the subaccount id, e.g. for calling the metering API for user-based pricing.
  • In case you are interested in the customers tenant GUID make use of getZoneId() instead!
  • In upcoming releases - especially for new subaccounts - subaccount id will no longer match the tenant GUID which is provided via the xsuaa access token as zid claim or via the ias oidc token as zone_uuid claim.

2.7.1

  • [java-security]
    • XSUserInfoAdapter provides now the subdomain that is required for token exchange via getSubdomain() method.
    • Avoid warning messages "IAS Service is not yet supported!". #273
    • rename Token claim "sap_uid" to „user_uuid“.
    • Token Key Cache can now be customized via XsuaaTokenAuthenticator.
    • XSUserInfoAdapter supports requestTokenForUser() method.
    • set validators to package private, you can customize the JWT validators using the JwtValidatorBuilder.
    • Create validation results lazy. Avoid false warning validation results from JwtAudienceValidator (#290), e.g.
      Jwt token with audience [<appId>, uaa] is not issued for these clientIds: [<appId>].
  • [spring-xsuaa] Improve logs of Audience Validators.
  • [spring-xsuaa-starter] Upgrade Spring versions:
    • spring.boot.version: 2.2.6.RELEASE --> 2.3.0.RELEASE
    • spring.core.version: 5.2.5.RELEASE --> 5.2.6.RELEASE
    • spring.security.version: 5.3.1.RELEASE --> 5.3.2.RELEASE
    • spring.security.oauth2: 2.4.0.RELEASE -> 2.4.1.RELEASE
  • [spring-xsuaa-test]
    • renamed file privateKey.txt to spring-xsuaa-privateKey.txt and publicKey.txt to spring-xsuaa-publicKey.txt to avoid name clashes in context of CAP, which results in a strange IllegalArgumentException:failed to construct sequence from byte[]: DEF length 1213 object truncated by 2. This can happen when you use java-security-test and spring-xsuaa-test in parallel.
    • For new applications spring-xsuaa-test can be replaced in favor of java-security-test for unit testing. For testing your app locally you can setup your local environment with the VCAP_SERVICES in order to test with your XSUAA instance on Cloud Foundry.
  • [token-client]
    • more detailed debug logs and details to exception; decoded token gets logged.
    • supports optional scope parameter to reduce scopes that are provided via CientCredentialsTokenFlow or UserTokenFlow.
    • By default requested tokens are now cached. You can disable the cache globally or per request as described here.
    • never log an encoded token! Instead you can log the OAuth2TokenResponse itself: the toString() method provides the content of the decoded token (clear text). Be aware that this contains sensitive user data.

2.7.0

  • [token-client] By default requested tokens are now cached. You can disable the cache globally or per request as described here.
  • [java-security]
    • XSUserInfoAdapter provides now the subdomain that is required for token exchange via getSubdomain() method.
    • Avoid warning messages "IAS Service is not yet supported!".
  • [spring-xsuaa-test]
    • renamed file privateKey.txt to spring-xsuaa-privateKey.txt and publicKey.txt to spring-xsuaa-publicKey.txt to avoid name clashes in context of CAP, which results in a strange IllegalArgumentException:failed to construct sequence from byte[]: DEF length 1213 object truncated by 2.

  • [java-security] JwtAudienceValidator Support Audience Validation of Xsuaa Broker clones (multiple xsuaa bindings): NGPBUG-111540.
  • [java-security-test] Basic support fo JUnit 5 (Jupiter).
  • [java-security-test] Deprecation: SecurityTestRule#getWireMockRule() needs to be replaced by getWireMockServer().
  • [java-security-test] One instance of SecurityTestRule should run only one WireMock server. With that @ClassRule SecurityTestRule can be declared in a base class.

2.5.3

  • [spring-xsuaa] XsuaaJwtDecoder supports verificationkey from VCAP_SERVICES as fallback public key.
  • [spring-xsuaa] when using auto-configuration and expose your own RestTemplate RestOperations bean, have a look at this documentation.
  • [java-security-test] JwtGenerator supports withLocalScopes().
  • [java-security] SapIdToken should return value of claim "sap_uid" (SAPGlobalUserID) as Principal name.
  • [java-security] JwtAudienceValidator Support Audience Validation of Xsuaa Broker clones: NGPBUG-111540.
  • [java-api] enhanced with config interfaces, which are relevant for SAP Java Buildpack.
  • [api] changes XSUserInfoException from Exception to RuntimeException. This reflects the json-lib change in java-container-security (version 3.12.0).

2.5.2

  • [java-api], [java-security], [token-client] works with logger api slf4j-api and does no longer provide the slf4j-implementation. Please have a look at the java-security/README.md#logging documentation.
  • [xsuaa-spring-boot-starter] update spring-boot (security) dependency versions #239.
  • [java-security-test] SecurityTestRule.setKeys allows to customize private/public keys that are located in the resource path, e.g. src/main/resources or src/test/resources.
  • [java-security-test] configures the modulus of the public key provided by WireMock. With that the public key can be consumed by the Nimbus Jwt decoder.
  • [samples/spring-security-xsuaa-usage] demonstrates how to setup JUnit tests using java-security-test library.

2.5.1

  • [java-api] As preparation for the SAP Java Buildpack the interfaces, as well as the SecurityContext is extracted to java-api.
  • [java-security] AccessTokens provided via the SpringSecurityContext should also support the hasLocalScope method.

2.5.0

  • [java-security-test] JwtGenerator.withClaimsFromFile accepts claims from a file.
  • [java-security] Provides with SpringSecurityContext an alternative way of accessing jwt tokens for Spring applications in asynchronous threads.
  • [token-client] The UserTokenFlow has used the "user_token" grant type together with the "refresh_token" grant type in order to do the token exchange. After the consumption of UAA 4.27 we can adapt the grant type "urn:ietf:params:oauth:grant-type:jwt-bearer". This reduces the round trips to the XSUAA from 2 to 1. Further, it eliminates the need for the user to have scope "uaa.user". The feature flag xsuaa.userTokenFlow.useJwtBearer has become obsolete.

2.4.5

  • [java-security] Initial / released version of the new plain Java security libraries as documented here.

2.3.2

  • [spring-xsuaa] Fix vulnerability issues and increased Spring versions.

  • [token-client] Supports basically JWT Bearer Token Grant as documented here.
  • [token-client] Bug fix for state issue in HttpHeaderFactor (#200) that causes interference between different types of token flows.
  • [spring-xsuaa] xsuaa bindings of plan apiaccess does not cause an error, as they get ignored for token validation.

2.2.0

  • [spring-xsuaa] PropertySourceFactory supports custom property sources and default can optionally be disabled with spring.xsuaa.disable-default-property-source=true
  • [spring-xsuaa] Supports Spring Core 5.2.0.RELEASEand Spring Boot 2.2.0.RELEASE
  • [spring-xsuaa] Deprecates TokenUrlUtils in favor of OAuth2ServiceEndpointsProvider
  • Internally, we've cleaned up maven dependencies (converged versions) and
    • removed transient dependency of spring-security-oauth2 to jackson.
    • introduced org.owasp.dependency-check-maven which performs CVSS checks.
  • [token-client] Supports password token flows as documented here.

2.1.0

  • token-client library supports Apache Http Client (without any Spring dependencies). Have also a look at the java-tokenclient-usage sample application.
  • Fix CVE-2018-1000613 by removing unnecessary dependencies (issue 144).
  • Makes XsuaaMockWebServer more robust.

2.0.0

  • Deleted package com.sap.xs2.security.container in order to avoid Class Loader issues, when an application makes use of SAP-libraries using the SAP-internal container lib like CAP.
    • As already mentioned use SpringSecurityContext class instead of SecurityContext class.
  • Removed deprecated methods:
    • XsuaaServiceConfiguration.getTokenUrl()
    • XsuaaToken.getClaimAccessor() is not required anymore as Xsuaa itself implements JwtClaimAccessor .
  • Deprecated TokenBroker interface and its implementation UaaTokenBroker, as this is going to be replaced with the OAuth2TokenService interface which is provided by the new token-client library. If you wish to configure / pass your RestTemplate you can pass an instance of OAuth2TokenService:
new TokenBrokerResolver(
        <<your configuration>>,
        <<your cache>>,
        new XsuaaOAuth2TokenService(<<your restTemplate>>),
        <<your authenticationInformationExtractor>>);
  • TokenUlrUtils class is now package protected and will be deleted with version.
  • token-client library supports basically Password-Grant Access Tokens.

1.7.0

  • We now provide a new slim token-client library with a XsuaaTokenFlows class, which serves as a factory for the different flows (user, refresh and client-credentials). This deprecates the existing Token.requestToken(XSTokenRequest) API.

    • The token-client library can be used by plain Java applications.
    • Auto-configuration is provided for Spring Boot applications only, when using XSUAA Spring Boot Starter.

  • ANNOUNCEMENT: Please be aware that with version 2.0.0 we want to get rid of package com.sap.xs2.security.container in order to avoid Class Loader issues, when an application makes use of SAP-libraries using the SAP-internal container lib.

1.6.0

  • Provides spring starter for spring-xsuaa, which enables auto-configuration
  • Supports reactive ServerHttpSecurity (Spring webflux). Have a look at the (webflux sample application)[samples/spring-webflux-security-xsuaa-usage/README.md]
  • Some enhancements for XSUAA integration
  • To make sure that the Spring SecurityContext is always initialized with a validated token use SpringSecurityContext.init() method as documented here
  • Use SpringSecurityContext instead of SecurityContext, which gets deprecated in this version.

Incompatible changes

  • As of version 1.6.0 you need to make use of XSUAA Spring Boot Starter in order to leverage auto-configuration (see "Troubleshoot" section here)

1.5.0

  • Supports jku URI which is provided as part of the JSON Web Signature (JWS). The jku of the Jwt token header references the public key URI of the Xsuaa OAuth Authorization Server, and needs to match to the xsuaa.uaadomain.
  • Completely customizable auto-configurations so that apps can override the spring-xsuaa defaults:
    • auto-configuration for Xsuaa OAuth Authorization Server is documented here.
    • auto-configuration for Xsuaa Mock Server configuration can be found here.
  • Uses apache slf4j Logger for better log analysis on Cloud Foundry. This is provided with org.springframework.boot:spring-boot-starter-logging.
  • Improves and enhances sample application.
  • Renames class TokenImpl to XsuaaToken. Furthermore for convenience XsuaaToken subclasses org.springframework.security.oauth2.jwt.Jwt.
  • Subclassing of TokenAuthenticationConverter is no longer allowed, instead TokenAuthenticationConverter can be configured with your own AuthoritiesExtractor implementation (an example can be found here).
  • Please note that the port of the mock web server that is provided with the xsuaa mock library had to be defined statically. It runs now always on port 33195.
  • Find more complex examples here: https://github.com/SAP/cloud-application-security-sample
